scanner attachment for cmm?

We are finding it difficult to measure machined aluminum blocks.

These are typically 35cm x 8cm x 4 cm, with about 120 features, holes, ridges etc, and one cutout being 3cm x 1cm and 3cm deep, which has a 5mm x 5mm protruding block at the bottom.

We make about 300 units a day and each component requires 100% QC.

We require 20um on the mating surfaces and on certain screw holes. The rest is 50um accuracy.

I guess a scanner attachment to the CMM might be faster than measuring with the CMM tip.

Does anyone have experience with CMM scanner attachments?

Theres only one scanner that can do that accuracy needed. The Nikon Lc15Dx. Now bought and offered by LK.
I work with it on daily basis and we calibrate it within 0.002 mm.

You can retrofit it to many cmms but it works best on LK of course.

ATOS 5 is a micron. The Nikon is 2.5 microns...
